The 1992 ANSI/IEEE standard (See Listed limit table) specifies a minimum separation distance of 20 cm for performing reliable field measurements to determine adherence to MPE limits. If the minimum separation distance between a transmitter and nearby persons is more than 20 cm under normal operating conditions, compliance with MPE limits may be determined at such distance from the transmitter. When applicable, operation instructions and prominent warning labels may be used to alert the exposed persons to maintain a specified distance from the transmitter or to limit their exposure durations and usage conditions to ensure compliance. 3.2 FCC LIMITS FOR MAXIMUM PERMISSIBLE EXPOSURE (MPE) LIMITS FOR GENERAL POPULATION / UNCONTROLLED EXPOSURE Frequency Range (MHz) E-field Strength (E) (V/m) Magnetic Field Strength (H) (A/m) Power Density (S) (mW/cm 2 ) Averaging Time |E| 2 , |H| 2 or S (Minutes) 0.3 -- 1.34 614 1.63 (100)* 30 1.34 -- 30 824/f 2.19/f (180/f 2 )* 30 30 -- 300 27.5 0.073 0.2 30 300 -- 1500 -- -- f/1500 30 1500 -- 100,000 -- -- 1.0 30 *Note: 1. f= Frequency in MHz * Plane-wave Equivalent Power Density 2. The averaging time for General Population/Uncontrolled exposure to fixed transmitters is not applicable for mobile and portable transmitters. See 47 CFR §§2.1091 and 2.1093 on source-based time-averaging requirement for mobile and portable transmitters. 3.3 CLASSIFICATION OF THE ASSESSMENT METHODS According to user manual, The antenna of the product, under normal use condition is at least 151.8cm away from the body of the user. Warning statement to the user for keeping at least 151.8cm separation distance and the prohibition of operating to a person has been printed on the user’s manual. So, this product under normal use is located on electromagnetic far field between the human body. S=PG/4πR² Where: S=power density P=power input to antenna G=power gain of the antenna in the direction of interest relative to an isotropic radiator R=distance to the center of radiation of the antenna 3.4 EUT OPERATION CONDITION Make the EUT to transmit at Bottom channel, Middle channel and Top channel individually. 3.5 TEST RESULTS Note: report the worst result in this part Antenna Gain=2.5dBi (Numeric 1.78), π=3.141 TEST Frequency (MHz) Tune-up Tolerance (dBm) Max tune-up (dBm) Max tune-up (mW) Power Density (mW/cm 2 ) Power Density Limit (mW/cm 2 ) Result (Pass/Fail) 462.6500 46.5±0.5 47 50118.7234 0.308140322 0.3084 Pass Note: 1.

MAXIMUMN TRANSMITTER POWER 10.1 PROVISIONS APPLICABLE FCC Part 95.1767 For GMRS, the maximum permissible transmitter output power effective radiated power (e.r.p.) as follows. This section contains transmitting power limits for GMRS stations. The maximum transmitting power depends on which channels are being used and the type of station. 462/467 MHz main channels. The limits in this paragraph apply to stations transmitting on any of the 462 MHz main channels or any of the 467 MHz main channels. Each GMRS transmitter type must be capable of operating within the allowable power range. GMRS licensees are responsible for ensuring that their GMRS stations operate in compliance with these limits. The transmitter output power of mobile, repeater and base stations must not exceed 50 Watts. The transmitter output power of fixed stations must not exceed 15 Watts. 462 MHz interstitial channels. The effective radiated power (ERP) of mobile, hand-held portable and base stations transmitting on the 462 MHz interstitial channels must not exceed 5 Watts. (467 MHz interstitial channels. The effective radiated power (ERP) of hand-held portable units transmitting on the 467 MHz interstitial channels must not exceed 0.5 Watt. Each GMRS transmitter type capable of transmitting on these channels must be designed such that the ERP does not exceed 0.5 Watt. 10.2 MEASUREMENT METHOD 10) EUT was placed on a 0.8 or 1.5meter high non-conductive stand at a 3 meter test distance from the receive antenna. A receiving antenna was placed on the antenna mast 3 meters from the EUT for emission measurements.
